Xfinity Won’t Cancel My Service

I moved and transferred my service. A month later I get charged for two accounts. I call to understand why the transfer didn’t cancel both accounts. The rep assured me he cancelled the service at my previous house and refunded me for the month. I check a few days later and see there is no confirmation of cancellation nor is my account saying anything about cancellation. I call again. I speak with a representative and same thing assured me it’s cancelled and I will receive a confirmation in a few hours. I told that’s not acceptable, I should receive confirmation immediately. He put me on hold for what seemed like forever and I hung up. This is such a waste of unnecessary time. I will be canceling all my services with this provider I dislike a company that takes advantage of customers. They shouldn’t be in business.
